| titleOfInvention | Production method of aromatic polycarbonate resin having increased molecular weight |
| abstract | Process for producing a highly polymerized aromatic polycarbonate resin comprising a high polymerization step of reacting an aromatic polycarbonate prepolymer with an aliphatic diol compound in the presence of a transesterification catalyst to obtain a highly polymerized aromatic polycarbonate resin, in the that the weight average molecular weight of the highly polymerized aromatic polycarbonate resin is 5000 or higher than the weight average molecular weight of the aromatic polycarbonate prepolymer; in which the aliphatic diol is represented by one of the following formulas (g2) and (g3): ** Formula ** in which, in the formula (g2), Ra and Rb each independently represent a hydrogen atom, a halogen atom, a linear or branched alkyl group with 1 to 30 carbon atoms optionally having an oxygen atom or a halogen atom, a cycloalkyl group with 3 to 30 carbon atoms optionally having an oxygen atom or a halogen atom, an aryl group with 6 to 30 carbon atoms optionally having an oxygen atom or a halogen atom, or an alkoxy group with 1 to 15 carbon atoms optionally having an oxygen atom or a halogen atom, and Ra and Rb can join each other to form a ring; R1 to R4 each independently represent a halogen atom, or a linear or branched alkyl group with 1 to 5 carbon atoms; and n represents an integer from 0 to 30; ** Formula ** wherein, in formula (g3), Ra and Rb each independently represent a halogen atom, a linear or branched alkyl group with 1 to 30 atoms carbon having an oxygen atom or a halogen atom, a cycloalkyl group with 3 to 30 carbon atoms optionally having an oxygen atom or a halogen atom, or an alkoxy group with 1 to 15 carbon atoms optionally having an oxygen atom or a halogen atom, and Ra and Rb can be joined together to form a ring. |
